Hmmm interesting. Well, the 650 horse is a rough guess because I'm going to use the new trick flow 240 head for the big blocks, and a 615/621 lift, 260/264 @.050 duration solid flat tappet from Hughes, at either 10.51 or 11-1 compression. I was reading a forum the other day on here and they had a 470 stroker with the same heads, not sure on cam, but 10.5-1 on pump gas and it made 675 horse @ 6,100 rpm. Im most likely going to use a factory forged crank unless a cast crank will hold up. Id like a forged one though.
Can`t speak for a girdle but will say I`ve been runnin the same 413 forged crank for 15 years and looked good on last two freshen ups and I assume I make that much w/my 470. Sounds like a nice combo and welcome aboard.............
